My sound was working fine until recently when my laptop was struggling to start up Windows. I tried selecting the startup option "Last known working configuration" (or similar) , which fixed my startup problems, but ever since that point, I have had no sound on my laptop.
If I place my cursor over the sound icon in the taskbar, it says "No Audio Output Device is installed".
The Device Manager shows currently that there are the following sound devices:
ATI High Definition Audio Device
IDT High Definition Audio CODEC
both of these have a yellow triangle with an exclamation mark within their icons.
It is a Studio 1558 (64 bit) laptop running Windows 7.
Could you please suggest how I might go about getting my sound back?

I did what you suggest above and after the reboot, a Troubleshooter was launched. I followed it right through to the end and the problem was not resolved.
Relative to my original post, nothing has changed. The "No Audio Output Device is installed" is still there and both of the sound devices still have a yellow triangle with an exclamation mark within their icons in Device Manager.
You may uninstall and then re-install the audio drivers from 'Device Manager' by following the steps below:
If the issue persists, paste the screenshot of 'Device Manager'.
Please share the findings.
I have done this and the only thing that I noticed different is that the message at the taskbar sound icon changed to "The audio service is not running" while the installation of the audio drivers was taking place, before the second restart. After the 2nd restart, the message had gone back to "No Audio Output Device is installed", as before.
The screendump of the Task Manager looks as follows:
The end result - yet again, no change. :o(
Is there any way I can reinstall Windows 7 without doing a complete refresh? I.e. reinstall it without affecting any data or programs?
You may install the drivers in following order from the links below:
If the issue persists, you may also try the Microsoft Fix it from link: http://bit.ly/JvQScV
Click on 'Run Now' and follow the prompts on screen.
If the issue still persists, you can try a system restore and restore it to the date prior this issue occurred. All the data on computer will be safe but the applications that you have installed after that restore point, you might need to re-install it.
Open System Restore by clicking the Start button . In the search box, type System Restore --> Click it. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Follow the prompts to choose a restore point and restore your computer.
If the issue persists, you may restore your computer to default factory settings. This step will lead to data (pictures, documents, programs, music) loss. Please perform a data backup prior to this step. Please disconnect any external peripherals (printer, scanner or any USB device) as well.

Please reply for further clarifications.
You don't get any audio, but your problem may not be with the audio driver. Your Radeon video card has audio components (hence the ATI video driver). Try to install in the following order:
* Intel Chipset
* IDT HD Audio
* ATI Video Card (it looks like there is a conflict between the two audio devices, hence the bang)
